Abhishek Bachchan, who is playing a politician in R Balakrishnan's upcoming film
, modelled his look on the young leaders Sachin Pilot and Milind Deora.
The 33-year-old actor plays Amol Arte, a young politician and MP from Lucknow in the film, which is releasing on December 4.
"I have modelled my look after Sachin Pilot and Milind Deora. There were no special efforts taken for my look in the film because we wanted to keep the character as normal as possible," the junion Bachchan told PTI.
Abhishek essays the role of reel father of his real-life dad in the movie, which he says is a role of lifetime.
The 67-year-old superstar plays a 13-year-old child suffering from progeria in the film, a rare genetic disorder which accelerates ageing.
"This is a role of a lifetime. Very few actors get such an experience and opportunity... Especially a son to play father to his own 'Paa'. We are only and perhaps the first actor father-son duo to have played themselves in a role reversal," Abhishek says.
"We wanted to maintain the uniqueness of Dad's look in the film and did not want to overload it with different types of looks for other characters," the actor says.
Abhishek has previously shared screen with his legendary father in movies like 'Bunty Aur Babli', 'Sarkar', 'Kabhi Alvida Naa Kahna' and 'Delhi 6'. 'Paa' is his fifth film with Amitabh.

Besides, we had to maintain the uniqueness of Dad's look in the film and did not want to overload it with different types of looks for other characters, he added.
The actor said that Balki made him shave "which I had not done for 5-6 years."
Abhishek also lost 15 kg when he shot for 'Paa'.
"I had lost weight for 'Raavan' and Mani Ratnam took ill during the making which delayed the shooting schedule for six months. 'Paa' was scheduled to go on floors in December this year after I finish 'Raavan'. Due to the delay in Raavan, we completed 'Paa' during that period," he said.
On working with his father in movies, Abhishek said "Paa" is my fifth film with him. I am used to pressures of sharing screen space with him. I have never thought about the pressures and expectations as a challenge. I prefer using that energy to better my performance."
"I got to spend time with him as for the last couple of years, my films have been shot outside Mumbai or abroad. Also due to the make up, it was easy to forget the real person behind the mask," he added.
